DESIGN BY VIC SMEED
The application of a rigid 'wing' to racing models was demonstrated by top innovative model designer Roger Stollery, who won the 1966 10-rater vane championship with Warlord. This yacht featured a wing mast 72in. or so high, 6in. wide at the base and 3in. at the head; there was at the time no restriction on mast and spar sizes in this class, but a limit was subsequently very rapidly applied, especially when Roger demonstrated after the race that the boat would sail quite well with the mast alone, without the 1,000 sq. in. of sail cloth normally attached!
Over the years there have been various experiments with small models, some with a row of rigid airfoils and some with one or possibly two 'wings'. An Australian, T. D. Seabrook, followed the Miss Nylex arrangement with a 'Marblehead' rig,
CLOTH SAILS ARE TRADITIONAL — hemp, flax, cotton, and more recently synthetics because of the necessity of reefing and furling square sails according to the wind strength and, in the case of fore and aft sails, the need for them to adopt the same curve on opposite tacks. It is perhaps worth mentioning that the first use of synthetics was on models, when a specially varnished Terylene made for submarine cable insulation was found to be an excellent material for model racing sails.
